The check engine light is on in my 2019 SLC (only 42K miles) and the car is emitting a lot of smoke from the exhaust pipe and it is hesitating while driving it. I almost got rear ended. I took it to the dealership and the fault code comes back as: P052E71 - The valve crankcase ventilation has a malfunction. The actuator is blocked. I searched online and this appears to be a very common and expensive issue on all Mercedes models. It goes out often in them and the dealer says it is NOT covered under the MB warranty. As it is an emissions issue, I understand that my car will not pass smog check without it and I reside in California where it has to pass smog inspection to register it. Even after I get it repaired, the propensity for it to have to be replaced again in the future is high. Please issue a safety recall issue for this problem.
